Elevation gain not showing in Outdoor Cycle
I've just recently gotten back out on my bike for the first couple of times since I've had an Apple Watch (4, WatchOS 5.3).
When I start an Outdoor Cycle activity, the watch seems to record my pulse, distance traveled, average speed, and elapsed time just fine.
There's also a metric on my screen for Elevation, but no matter how many hills I attack during my ride, this metric stays at zero.
Why is it not recording elevation? What do I need to turn on?
